SLElGH-BOB.

SPECIFICATION forming part of Letters Patent No. 441,200, dated November 25, 1890.

Application filed May 31, 1890. Serial No. 358,736. (No model.)

To all whom it may concern:

Be it known that I, HERMAN J. SIMON, a citizen of the United States, residing at Peshtigo, in the county of Marinette and State of Visconsin, have invented a new and useful Improvement in a Sleigh-Bob, of which the following is a specification.

, My invention relates more particularly to sleigh-bobs for use under carriage-bodies in I place of the wheels thereof when it is desired to change their mode of movement from wheels to runners, and is an improvement upon a patent granted to me December 4, 1888, No. 393,863; and it consists in a modification in the formation of the sleigh-beam and the manner of connecting it to the sleighrunne'rs, a modification in the formation of the connecting-piece which form said connection in the form of the sleigh knees or standards, and of the manner of connecting said standards and the aforesaid connecting-piece to each other and to the sleigh-runner, and also a modification in the formation of the bottom part of the boxes, in which the carrlage-axle is to be journaled; and the object of the improvement is to lessen the cost of their construction and to provide lightness and strength therefor. I attain these objects by the construction illustrated in the accompanying drawings, in which-- Figure 1 is a rear view of a sleigh-bob embodying my invention; Fig. 2, a top view of the same, the parts in dotted lines representing the runners when set for a track of wider gage than those in Fig. 1; Fig. 3, a vertical section longitudinally of the runner upon the line a a of Fig. 1; Fig. 4, a vertical section upon said line of the sleigh-beam, showing an end view of the supporting-socket thereof, the manner of connecting braces thereto, and also showing an end view of one modification of a box for supporting a journal of a carriage-axle and the manner of connecting the two sections of the lower half of said box to each other and to the sleigh-beam. Fig. 5 is a top view of the sleigh-beam socket-piece; Fig. 6, a vertical section of said socket-piece upon the line b b of Fig. 5, showing the socket for receiving the top end of the sleigh knees orstandards; and Fig. '7, an end view showing amodification in the construction of the socket-piece illustrated in the foregoing figures. Figs. 4, 5, 6, and 7 are upon the same scale with reference to each other, but upon an enlarged scale with reference to Figs. 1, 2, and 3.

Similar figures of reference indicate like parts in the several views.

The figure 1 indicates the sleigh-runners; 2, the sleigh knees or standards which support the beam; 3, the raves; 4, the fenders; 5, the sleigh-beam; 6, the socket-piece which connects the standards 2 2 and beam 5; 7, boxes in which the axles of the carriage are journaled under which the sleigh-bob is to be used; 8, braces connecting the inner end of the socket-piece 6, the standards 2, and the runner; 9, braces connecting the outer end of said socket-piece and standards; 10, a socket upon the lower side of the socket-piece 6; l1, bolts connecting braces 8 and 9 to the ears 6" of the socket piece 6; 12, a bolt passing through a hole 10 in the socket 10, and 13 bolt-holes in the socket-piece 6 for connecting it to other parts.

The runners, standards, raves, and fenders are formed of wood of that class which is known among carriage and sleigh makers as bent stock, and are connected together in the usual manner. The socket-piece is of metal, preferably, and may be either cast or forged, malleable iron being well adapted for it. The sleigh-beam 6, I make of the ordinary rolled T-iron of commerce. The braces 8 and 9 may be forged or of malleable castmetal, as preferred, and for the boxes, in which the carriage-axles are journaled, I prefer for its cheapness and adaptability a cast metal.

The socket-piece 6 may be formed, as shown in Figs. 3, 4, and 5, of a single piece, or it may for convenience in casting the same be cast in two parts, and said parts bolted together with the bolts 11 and 12, as shown in Fig. 7. Said socket-piece has upon its upper side at each end and upon both sides thereof,

cars or lugs 6, which are turned over so as IOO UNITED STATES JAMES SIMPSON, OF MOKEESPORT, PENNSYLVANIA.

TANG. FOR PlPE-SKELPS.

SPECIFICATION forming part of Letters Patent No. 441,201, dated November 25, 1890.

Application filed August 11, 1890.

To all whom it may concern:

Be it known that 1, JAMES SIMPSON, of Mc- Keesport, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Skelp-Tangs for Pipe-Velding, of which the following is a full, clear, and exact description.

In welding pipe by the usual process of drawing a heated skelp or plate of iron through a bell which turns up its edges and causes them to meet and to weld together, it is customary to employ a round tang or bar of iron, which is welded to the skelp-iron and aifords the means for connecting it to the buggy or drawing device. Many attempts have been made to replace this expensive and inconvenient device by gripping-tongs, &c., but heretofore these have failed to give satisfactory results, owing, principally, to the fact that the connection between the tang and the skelp has been insufficiently rigid and secure.

In making pipe of large size it is especially necessary that such connections should be strong and rigid, and to afford this is the object of my invention.

The invention is illustrated in the accompanying drawings, in which- Figure 1 shows in plan view my improved device for attaching the tang. Fig. 2 is a cross-section on the line II II of Fig. 1. Fig. 3 shows in plan view a device of modified construction. Fig. 4 is a cross-section on the line IV IV of Fig. 3.

Referring to Figs. 1 and 2, a is the skelp, and b is the tang. The tang is a bar of iron, the outer end of which may be circular in cross-section, while the end, which is fitted to the skelp, is preferably of the form shown in Fig. 2, being oblong in cross-section and shaped to conform to the curvature of the Serial No. 361,629. (No model.)

and through the slots in the bolts. This key is preferably tapered, and by bearing on one side against the base of the groove e, and on the other side against the ends of the slots in the bolts, it draws the heads of the bolts and the tang toward each other so as to cause them to clamp tightly the interposed skelp and to hold the tang to the skelp with great rigidity. In order that the heads of the bolts may project as little as possible at the outside of the skelp, I prefer to make them of the form shown in Fig. 2 to conform to the curvature of the sk-elp. After the skelp has been drawn through the bell the tang may be removed by Withdrawing the key and removing the bolts. In the device just described the bolt-holes are situate'in the median line of the tang and only onekey need be used. In the modified construction shown in Figs. 3 and 4, there are three boltholes, not in line with each other. The tang is provided with three separate grooves e, and three keys dare employed, one for each groove and bolt.

Other constructions of my improved device will suggest themselves to those skilled in the art. I

Its advantages are numerous and it affords combined in one device the strength and rigid ity of the welded tang, together with the easy attachability and detachability which have been so much sought for by prior inventors but with unsatisfactory results.

I claim- 1. As a device for attaching a tang to a skelp, the combination, with the tang, of bolts passing through the sameand through the skelp, and a key or keys by which the bolts are held to the tang, substantially as and for the purposes described.

2. As a device for attaching a tang to a skelp, the combination, with the tang, of bolts adapted to pass through the tang and skelp, and a key or keys fitting in key-seats in the tang, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 7th day of August, A. D. 1890.

JAMES SIMPSON.
